Combine all marinade ingredients. Pour half the mixture over the chicken
and set in the refrigerator to marinate for at least 2 hours or up to 24 hours. Save the
remaining mixture for basting.

Prepare an outside grill with an oiled rack set 4 inches above the heat
source. On a gas grill, set the heat to high. Grill the chicken breasts for 3 to 4 minutes
on each side, turning once and basting with extra marinade, until the chicken is cooked
through.
